These days you find Navya Nair visiting the gym frequently. The star has set on a diet and exercise course to reduce her bulk. She abstains from her favourite food, the Malabar red rice. What she used to have three times a day, she has once a week now. Such is her determination to become slim. Now, why does she want to slim down? It looks like the taste of the Tamil moviegoers has changed. They no longer go for the chubby, tummy style Sundaris. That’s reason why even Jyothika slimmed down, reducing what was once considered her oomph factor, the tummy.
